Why are horseshe crabs more similar to arachnids than to crustaceans if they have more than four pairs of legs?

Because arachnids and crustaceans share a pair of appendages called chelicerae, which are specialized mouthparts that we find in both arachnids (Spiders) and horseshoe crabs. In fact, these mouth parts define the name of the entire subphylum to which these animals both belong, the Chelicerata. There are a few different types of chelicerae, but in arachnids, these would be the mouth parts that most people think of as 'fangs,' some which are of course venomous. In horseshoe crabs, they are the anterior-most (front-most) pair of appendages, look like small claws, and are used for feeding.

Are crabs arrachnids?
The class Arachnida includes animals with four pairs of legs. So mites, scorpions, false scorpions, harvestmen and vinegarones are all in the same class as spiders. Crabs are Crustacea. The only link between them is that both classes are arthropods. Sea Spiders are in a separate class altogether.Confusion and argument has raged over the position of Horseshoe Crabs. My understanding is that they are now generally accepted as arachnids

"True crabsare decapod crustaceans of the infraorder Brachyura," (http://en.wikipedia.org/wiki/Crab) and "many varieties of shellfish (crustaceans in particular) are actually closely related to insects and arachnids" (http://en.wikipedia.org/wiki/Shellfish).
